NDS3542 MPEG2 HD/MPEG4 HD Encoder Modulator

Product Overview

NDS3542A series products are DEXIN’s new breakthrough all-in-one devices which integrate encoding (MPEG-2 HD, MPEG-4/AVC H.264) and modulation (DVB-C, DVB-T, ISDB-T, or ATSC) to convert V/A signals into RF output. It has equipped with 4 HDMI channels input and 1 ASI input and output with 2 ASI ports and 1 UDP IP port.

It adopts inner drawer-type structural design which greatly facilitates the change of encoding modules (HDMI/CVBS/SDI/YPbPr/…) as needed.

The signals source could be from satellite receivers, closed-circuit television cameras, Blue-ray players, and antenna etc. Its output signals are to be received by TVs, STB and etc with corresponding standard.

With its various inputs available, our NDS3542A series products are wildly used in public places such as metro, market hall, theatre, hotels, resorts, and etc for advertising, monitoring, training and educating in company, schools, campuses, hospital… It’s a good choice to offer HD channels and more.
